Background

Fan refers to a tool for cooling by generating wind in hot days. The electric fan is a device which is driven by electricity to generate air flow, and the fan arranged in the electric fan rotates after being electrified, so that the electric fan is converted into natural wind to achieve the cooling effect. The blades of a ceiling fan are generally 3, the blades of a desk fan are generally 5, and the cross section of the common fan blades is generally curved. The width and angle of the fan blades are designed according to the load power of the motor. If the rotating speed is only determined without considering the power of the motor, the angle of the fan blade is more important, and if the angle of the fan blade is the same, the wind is larger with the fan blade width. And the design and manufacture of the fan blades are regularly and symmetrically structured, so that a uniform and stable wind source can be generated. Common flabellum fans include three-flabellum fans, four-flabellum fans, five-flabellum fans, double-layer fans and the like.
